Ageism is also often known as age discrimination. Ageism meaning is the practice of treating someone unjustly because of their age. This may manifest itself in the workplace as someone being passed over for a job or promotion, the denial of benefits to older employees, or the termination of employment prematurely. Ageist beliefs may be harmful to a victim’s health and cause them to be marginalized in their communities. Anti-discrimination rules are intended to protect individuals from discrimination against things such as ageism.
